The purpose of this study is to review the mobility-based textual research methods raised in Mobility and Foucault and apply them to textual analysis. This book contains seven articles applying Foucault's terms to mobility studies, giving intellectual stimulation to both studies. Since Foucault examined discipline power operated through the technology of distinguishing between rational/irrational and normal/abnormal, his works seem to a study of closed spaces like prisons. However, the authors of this book note that Foucault's works already had sufficient insight on mobility, and them actively incorporated it into mobility study. When we concentrate Foucault's works on mobility as a governmentality and a dispositif, the tension and dynamics between mobility and immobility are emphasized. And then it is possible to cross the simple dichotomy in mobility studies. This paper analyzes Kim Joong-hyuk's short story 1F/B1 by applying this method. This story describes a building manager who seems to be fixed in a building, but the mobility of him in the story goes through stereotypes and creates new spaces. Kim Hye-jin's short stories also represent mobility that cannot move and hesitates. These stories are important in that they show the mobility as a dispositif that constitutes the subject. When referring to the achievements of Mobility and Foucault, we read this narrative again by paying attention to the dynamics of mobility and immobility in the text. The significance of this paper is that it expands mobility-based textual research anew. While text analysis applying mobility study was usually focused on clearly mobile narratives such as travel statements and diaspora narratives, Mobility and Foucault drives new textual research by paying attention to the relationship between power and mobility, mobility and immobility dynamics. Therefore, this paper is significant in confirming the new meaning of the text revealed when paying attention to the representation of mobility in the narrative that no one seems to be mobile, and seeking to expand the mobility-based textual research method.

Emergence of new media platform had changed relationship between the broadcaster and the viewer, which used to form 'performer-audience' structure. This research has focused on the transition of 'streamer-viewer' role in single-media broadcasting, such as Youtube or Twitch, and identify how they progress group storytelling as a team. Walter Benjam and Leslie Marmon Silko's notion of 'story and storyteller' and Erving Goffman's 'social role theory' was used to define participants' role in new media broadcasting. channel, on Youtube, was selected and analyzed as example case. The domain of 'front stage' was broadened in recorded contents comparing to live streaming. The audience of live streaming is included to the front stage during the expansion. The role of streamer, game participant, and live stream contents viewer is also adjusted during the change, which leads to group-creation of the contents. Streamer plays a role of main-storyteller and suggest identity of the community. Game participants work as sub-storyteller, filling in the blank space in game storytelling and making it sophisticated. They also perform based on community's identity, which streamer has built in advance. Lastly, live steam viewers are intermittent sub-storyteller, which seldom add up the narrative. Though, their main role is to preserve identity of game broadcasting community by reacting according to community's identity. As a result, the game broadcasting narrative is developed by combining and adding up pieces of story made in different level and role of participants. The research redefine the role of viewer and storytelling method in new media, especially in single-person broadcasting. Considering the rapid shift in recent media and contents, a new approach to the streamer-veiwer role and group storytelling of this research can be one of the new method to analyze contents produced in new media, such as Youtube.

In the history of Korean literature, evaluations on 『Jirisan』 (Lee Byeong-ju) are bisected. Some evaluate it as a novel of authentic records which reproduces the history before and after the emancipation objectively while others say it takes advantage of anti-communistic ideology. This study analyzes that difference is resulted not from the distinction of perspectives but from cracks in the text. This is associated with the process of 『Jirisan』's publication. 『Jirisan』 was published serially in 『Sedae』 from 1972, and then, part of the manuscript was published in 1978 and the whole edition published in a series came to be republished in 1981. After that, in 1981 and 1985, part of the follow-up story was printed on the magazine, and then, with the memoirs of those two years as materials, the sixth and seventh volumes were again published through 'revision'. In other words, the publication of 『Jirisan』 is divided into that of the edition published in a series and that of the edition published in 1985 including the contents of revision. The theme of the work, 『Jirisan』 differs according to the point of its completion you may think of. This researcher pays attention to the difference of perspectives between the contents up to the fifth volume and those of the sixth and seventh volumes. Particularly, his evaluation on 'partisans' seems to have changed. In the edition published in a series, he extended 'partisans' into the independence movement in the Japanese colonial era under the Revitalizing Reforms system and adopted the representation of 'partisans' three-dimensionally whereas in the sixth and seventh volumes, he reproduced 'partisans' as beings that were the 'doctrinaire' and 'vicious' 'Reds' and had to be punished. In brief, with 『Jirisan』, he represented 'partisans' in the background of history before and after the emancipation and segmented the discourse, representation and ideology of the Cold War system, but in the process of revision, he stitched up 'partisans' as beings that were evil and losers. Consequently, with 『Jirisan』, he revealed the process of division and contention that proceeded around anti-communism/capitalism within the abyss of the 1970's to 80's and reproduced 'partisans' as beings that were either 'hostile (the Reds)' or 'unknown (losers)

The purpose of this study is to research the effects of desire for independence, possibility of start-up success and employment stability to the push-entrepreneurship through the push-entrepreneurship by a survey of employees in the middle age. The purpose of the creating start-up environment was encouraged the qualitative expansion of opportunity-driven start-up rather than the quantitative expansion of necessity-driven start-up for the economic growth and expanding employment. In spit of the employees had their own careers, skills, opportunities and market-experiences, In reality it is necessity-driven start-up that the quantitative expansion. The purpose of this study was to reflect process change by desire for independence, push-entrepreneurship and pull-entrepreneurship based on the possibility of start-up success and employment stability perceived by individual founders, changed process factor rather than the fixed result factor. The results are as follows. First, it was found that desire for independence makes a positive (+) effect on the pull-entrepreneurship and the push-entrepreneurship. Second, it was found that the possibility of start-up success makes a positive (+) effect on the pull-entrepreneurship and not effect on push-entrepreneurship. third, it was found that the employment stability makes a positive (+) effect on the pull-entrepreneurship and not effect on the push-entrepreneurship. Forth, it was found that desire for independence makes a positive (+) effect on the pull-entrepreneurship and mediating negative (-) effect on the push-entrepreneurship. The implication of this study was that potential entrepreneurs with desire for independence, rather than necessity-driven start-up due to unemployment, could be developed as pull-entrepreneurship improved the situation of push-entrepreneurship. In addition, it seems that entrepreneurship education and activation of entrepreneurship programs for employee with desire for independence expand opportunity-driven start-up after retirement.

As a tiered system of supports, School-Wide Positive Behavior Support (SWPBS) is an evidence-based practice in the educational system of Korea. An important aspect of SWPBS is the ongoing progress monitoring and evaluation of implementation fidelity. This study aimed to develop and validate the Korean Tier 3 School-Wide Positive Behavior Support Implementation Fidelity Checklist (KT3-FC). The preliminary KT3-FC consisted of a 37-item, 6-factor checklist. In the first phase of the study, 10 experts reported that the range of content validity of the KT3-FC was adequate. In the second phase of the study, 185 teachers (52 men and 133 women) who implemented SWPBS completed the KT3-FC, Individualized Supports Questionnaire, School Climate Questionnaire, School Discipline Practice Scale, and PBS Effectiveness Scale. An exploratory factor analysis resulted in a 5-factor structure, with 20 items, instead of 37 items, consisting of: (a) progress monitoring and evaluation of the individualized supports, (b) provision of supports by aligning and integrating mental health and SWPBS, (c) crisis management planning, (d) problem behavior assessment, and (e) establishment of individualized support team. The internal consistency of the KT3-FC was good (full scale α = .950, sub-factor α = .888 ~ .954). In addition, the KT3-FC showed good convergent validity, having statistically significant correlations with the Individualized Support Questionnaire, School Climate Questionnaire, School Discipline Practice Scale, and the PBS Effectiveness Scale. Finally, the confirmatory factor analysis showed that the 5-factor model of the KT3-FC had some good model fits, indicating that the newly developed fidelity measure could be a reliable and valid tool to assess the implementation of Tier 3 supports in Korean schools. Accordingly, the KT3-FC could contribute to implement SWPBS as an evidence-based behavioral intervention for Korean students.

This study investigates the effect of perch type and height on the growth performance, footpad dermatitis (FPD), blood parameters, behavioral characteristics, and meat quality of broilers. A total of 912 one-day-old male Ross 308 broilers (48.23±0.264 g) were subjected to a three x two factorial design of three types of perch (wood, steel, plastic) and two levels of perch height (10→30 cm change, 10 cm fixed) over a five-week experiment. Growth performance, perch availability, litter quality, FPD incidence, serum biochemical parameters, and meat quality of the broilers were evaluated. There were no significant differences in the body weight, feed conversion ratio, and biochemical parameters (except for aspartate aminotransferase), pH, color, and water holding capacity. The incidence of FPD was significantly higher in the plastic perch group than in the wood and steel perch groups (P<0.05) at five weeks of age. Perch use was high in the order of wood, steel, and plastic groups in the daytime and nighttime at one, three, and five weeks of age (P<0.05). Perch use was higher in the 10 cm fixed group than the 10→30 cm group (P<0.05). The shear force of the breast significantly increased in the order of wood, steel, and plastic groups (P<0.05). In conclusion, the group with a fixed perch height of 10 cm had high perch usage. Additionally, the use of wooden perches was higher than that of other materials, and it lowered the incidence of FPD in broilers.

Although varieties of silkworms, which have recently attracted attention as a health functional food, are being produced, studies on the differences in the functionality of different silkworm varieties are insufficient. Therefore, in this study, the antioxidant activities of different silkworm breeds bred in domestic farms were analyzed, and the potential for their cultivation as specialized varieties with excellent antioxidant function was investigated. To compare antioxidant activity, four varieties of silkworms, white Bakokjam, Golden silk, Yeonokjam, and Hanseongjam, were bred; water and ethanol extracts of these silkworms were prepared on the 3rd and 5th days of the 5th instar larval stage. The highest extraction yield was seen for the water extract from the Golden silk variety on the 3rd day of the 5th instar; the highest total phenolic compound and flavonoid contents were observed for the water extract (86.11±4.04 ㎍/mg GE) and 70% (v/v) ethanol extract (46.70±2.81 ㎍/mg QE). Bakokjam and Yeonokjam exhibited DPPH radical scavenging activity of up to 78% and showed the highest nitrite scavenging activity (85%) at pH 1.2. The maximum SOD-like activity of Yeonokjam was about 47%. Furthermore, 48 ㎍/ml of the Yeonokjam extract showed a reducing power of 0.7 abs, which was the best among the four varieties. Considering these results, the Yeonokjam (on the 3rd day of the 5th instar) had antioxidant activity and represents a silkworm cultivar that would be suitable for cultivation as a health food.

Objectives : The purpose of this study is to compare bleeding tendency of selective serotonin reuptake inhibitor (SSRI) and serotonin norepinephrine reuptake inhibitors (SNRI) using platelet function analyzer (PFA-100) in patients with major depressive disorder. Methods : This study is a prospective open-label study conducted by a single institution. A total of 41 subjects diagnosed with major depressive disorder under the DSM-5 diagnostic criteria participated in this study. The subjects were classified into SSRI (escitalopram) groups and SNRI (duloxetine) groups, respectively, according to random assignments. The closure time (CT) was measured using a platelet function analyzer (PFA-100) before each antidepressant was administered and after 6 weeks. Paired-sample t-test was conducted within each group to determine whether a specific antidepressant had an effect on closure time. In order to confirm the relative change in platelet function between the two groups, an independent sample t-test was conducted to compare and analyze the change in closure time between the two groups. Results : There was no significant changes in closure time (CEPI-CT, CADP-CT) before and 6 weeks after drug administration in the SSRI and SNRI groups, and there was no difference in the amount of changes in closure time between the two groups. Conclusions : Our results showed no difference in bleeding tendency between SSRI and SNRI. This study suggests that further large-scale studies on bleeding tendency for various antidepressants are needed in the future.

We conducted this study to derive the site index, which is a criterion for the planting of Robinia pseudoacacia, a honey plant, and to investigate the diameter distribution change by derived site index. We applied the Chapman-Richards equation model to estimate the site index of the Robinia pseudoacacia stand. The site index was distributed within the range of 16-22 when the base age was 30 years. The fitness index of the site index estimation model was low, but we judged that there was no problem in the application because the residual distribution of the equation had not shifted to one side. We used the Weibull diameter distribution function to determine the diameter distribution of the Robinia pseudoacacia stand by site index. We used the mean diameter and the dominant tree height as independent variables to present the diameter distribution, and our analysis procedure was to estimate and recover the parameters of the Weibull diameter distribution function. We used the mean diameter and the dominant tree height of the Robinia pseudoacacia stand to show distribution by diameter class, and the fitness index for dbh distribution estimation was about 80.5%. As a result of schematizing the diameter distribution by site indices as a 30-year-old, we found that the higher the site index, the more the curve of the diameter distribution moved to the right. This suggests that if the plantation were to be established in a high site index stand, considering the suitable trees on the site, the growth of Robinia pseudoacacia woul d become active, and not onl y the production of wood but al so the production of honey would increase. We therefore anticipate that the site index classification table and curve of this Robinia pseudoacacia stand will become the standard for decision making in the plantation and management of this tree.

The purpose of this study is to survey and analyze acorn production and characteristics of the Quercus acuta Thunb. according to the need for information on seed supply and seedling cultivation during the restoration of warm broad-leaved forests. For the survey, a total of 30 seed traps with a surface area of 1 m² were set up, 3 in each of 10 quadrats (8 in Wando, 1 in Haenam, and 1 in Jindo). The acorns that fell in the seed trap at the end of each month were collected from August to December each year between 2013 to 2016. The collected acorns were then classified into sound, damaged, decayed, or empty grade, and the number of acorns produced was calculated. In the case of sound acorns, acorn traits, such as length, diameter and weight of acorns without cupule, were measured. Duncan's multiple tests of acorn production and characteristics were conducted for comparative analysis of the annual average values with the values by year, stand, month, and treatment plot. The annual number of acorn dropped into the seed traps in each quadrat from 2013 to 2016 was 5-350 acorns/3 m² in 2013, 17-551 acorns/3 m² in 2014, 5-454 acorns/3 m² in 2015, and 14-705 acorns/3 m² in 2016. There was a large difference in acorn production between the quadrats, presumably attributed to the difference in the amount of light received due to the density of trees in the square. Annual acorn production per area was 335,000 acorns/ha in 2013, 932,000 acorns/ha in 2014, 556,000 acorns/ha in 2015, and 1,037,000 acorns/ha in 2016. That was a sharp variation of acorn production in the two-year cycle. As the fluctuation in the production of Q. acuta showed simultaneity between stands, it is judged that Quercus acuta Thunb. had a clear cycle of fruitfulness and fruitiness between forest objects. September showed the biggest amount of fallen acorns and largest damage from insect pests, indicating that preventing early fall of acorns could increase the fruiting period and enable mass production of sound acorns. There was no significant difference between annual average acorn length in each region. In the case of the acorn diameter and weight, the average values of acorns from Haenam were significantly higher than those from Wando and Jindo. There was no significant difference in the average annual acorn characteristics by month, and the average annual acorn length, diameter, and weight in November were 19.72mm, 12.23mm, and 1.64g, respectively, the highest between August and November.
